Association between adequate dietary protein and all-cause and cardiovascular mortality in patients with selective glomerular hypofiltration syndrome

Abstract

Aims: To determine the impact of dietary protein intake and protein sources on all-cause and cardiovascular mortality of selective glomerular hypofiltration syndrome (SGHS) patients. Methods: This study recruited participants from the National Health and Nutrition Examination Survey (NHANES) conducted between 1999 and 2004. Cox proportional hazard models and competing risk models were employed to investigate the effects of dietary protein intake and protein sources on all-cause and cardiovascular mortality in SGHS patients. Additionally, Cox regression models utilizing restricted cubic splines (RCS) were used to explore potential non-linear associations. Results: Over a median follow-up period of 204 months, 20.71% (449/2168) participants died, with 5.40% (117/2168) experiencing cardiovascular mortality. In the fully adjusted model, participants with the highest dietary protein intake (Q4, ≥107.13 g d−1) exhibited a 40% reduced risk of all-cause mortality (HR: 0.60, 95% CI: 0.39 to 0.94) and an 88% reduced risk of cardiovascular mortality (HR: 0.12, 95% CI: 0.04 to 0.35) compared to those with the lowest dietary protein intake (Q1, < 57.93 g d−1). Notably, non-red meat protein sources were found to reduce the risk of all-cause and cardiovascular mortality, whereas no significant association was observed with red meat consumption. Conclusion: Adequate dietary protein intake has been linked to a decreased risk of all-cause and cardiovascular mortality in individuals with selective glomerular hypofiltration syndromes. This protective effect seems to be primarily associated with protein obtained from non-red meat sources.
